I'll try my best to give you a perspective on what you should consider when moving to Doha.
I'm asuming you're single for now considering you're experience.

To live in India with the current salary you have 8.2lakhs thats sums upto Rs.50,000 to Rs.52,000 per month after tax?
Lets say an expensive city like Bangalore how much will you save?

2Bed 2 Bath apartment with swimming pool, gym facilities etc including maintenance(water+electricity) = Rs.24,000 pm
Maid = Rs.2000 pm
News Paper = Rs.100 pm
Cable TV= Rs.300 pm + initial deposit of Rs.3000
Internet = Rs.1200

If you want to buy a car a Maruthi-Suzuki Swift will cost you approx Rs.10,000pm(3 year loan) or Rs.6,000(5 yr loan)

Food & Drink
Well depnding on if you like to party or not(being in Bagalore;)) ur monthly food & dink expenses could be anywhere from Rs.5,000 to Rs.15,000

Other expenses
You can keep a buffer of Rs.10,000 for other expenses like clothes or dent on car or falling sick or joining salsa classes etc

Going home
Depends on where you're home town is how often you chose to travel.

Now the big question is if you're in Doha will you be able to live this kinda life style and manage to save too??? I'm not sure if you can but the others will be able to help you on that.I dream of a better tomorrow where Chickens can cross the Road without having their motives questioned - Unknown
